Custom antibody development

We offer world-leading antibody development platforms based on a proprietary RabMAb® rabbit monoclonal platform, a phage display platform (AxioMx), and a next-generation sequencing platform (NGS-RabMAb®)

ab24966 binds to murine CD154 with high affinity, blocks binding to CD40, and blocks CD154 function. Administration of this antibody to mice blocks the ability to mount primary and secondary immune responses to TD antigens, yet does not alter the immune response to TI antigens.

Target

Function

Mediates B-cell proliferation in the absence of co-stimulus as well as IgE production in the presence of IL-4. Involved in immunoglobulin class switching.Release of soluble CD40L from platelets is partially regulated by GP IIb/IIIa, actin polymerization, and an matrix metalloproteinases (MMP) inhibitor-sensitive pathway.

Tissue specificity

Specifically expressed on activated CD4+ T-lymphocytes.

Involvement in disease

Defects in CD40LG are the cause of X-linked immunodeficiency with hyper-IgM type 1 (HIGM1) [MIM:308230]; also known as X-linked hyper IgM syndrome (XHIM). HIGM1 is an immunoglobulin isotype switch defect characterized by elevated concentrations of serum IgM and decreased amounts of all other isotypes. Affected males present at an early age (usually within the first year of life) recurrent bacterial and opportunistic infections, including Pneumocystis carinii pneumonia and intractable diarrhea due to cryptosporidium infection. Despite substitution treatment with intravenous immunoglobulin, the overall prognosis is rather poor, with a death rate of about 10% before adolescence.

Sequence similarities

Belongs to the tumor necrosis factor family.

Post-translationalmodifications

The soluble form derives from the membrane form by proteolytic processing.N-linked glycan is a mixture of high mannose and complex type. Glycan structure does not influence binding affinity to CD40.Not O-glycosylated.
